Students will review:
This chapter helps students review the concepts in a Data Management unit of a standard college information systems course. Topics covered include:
- Elements of a database
- Models of database management systems (DBMS)
- Relational databases
- Text, numbers and multimedia
- Data warehousing and data mining
- Cloud computing and databases
1. What is Database Management? - How Databases Help Organizations
Organizations use large amounts of data. Database management makes it possible to organize and analyze these data. Learn why database management is important to support business operations.
2. Database Concepts and Structures: The Elements That Make Up a Database
Learn the fundamental elements of databases and how they are structured. One common data structure is a database table, which uses records and fields to organize data.
3. What is a Database Management System? - Purpose and Function
In this lesson, we will describe the purpose and functions of a database management system, as well as the advantages and disadvantages of using a database management system in an organization.
4. Models of Database Management Systems (DBMS)
Get to know the different models of database management systems and learn how each one is used to systematically organize large amounts of data in a logical manner.
5. What is a Relational Database? - Elements, Design & Advantages
The relational database is the most widely used type of database management system. Learn how the relational database organizes data using tables, keys and associations.
6. Types of Data: Text, Numbers & Multimedia
Discuss the basic types of data found in databases. These include character strings, integers, decimals, images, audio, video and other multimedia types.
7. Structured Query Language: Manipulating Databases Using SQL
Describe how to manipulate a database using the logic of Structured Query Language. Learn the basic syntax to write database queries in SQL using the SELECT statement.
8. Data Warehousing and Data Mining: Information for Business Intelligence
Collections of databases that work together are called data warehouses. This makes it possible to integrate data from multiple databases. Data mining is used to help individuals and organizations make better decisions.
9. Database Administration and Security: Definition and Purpose
A database administrator, or DBA, plays a critical role in managing the databases of an organization. Learn about the various roles of a DBA and the tools used to keep data safe and secure.
10. Cloud Computing and Databases: Technology to Improve Database Management
Cloud computing uses a network of computers to provide services that otherwise would be provided by a single computer or computer server. Learn how cloud computing works and how it allows you to use the same database on multiple devices in this video lesson.
11. What is a Data Flow Diagram?
In this lesson, you'll learn what a data flow diagram is, how it is different from a flow chart, and some common uses for data flow diagrams. You'll also find out how to create your own simple data flow diagram.
12. What are Databases? - Examples & Types
In this lesson, we'll be looking at databases, which are computer mechanisms for storing and retrieving data. Test your knowledge following the lesson with a quiz.
13. Arithmetic Logic Unit (ALU): Definition, Design & Function
An arithmetic logic unit (ALU) represents the fundamental building block of the central processing unit of a computer. An ALU is a digital circuit used to perform arithmetic and logic operations.
14. What is a Number Sentence? - Definition & Examples
In this lesson, find out what elements are required for a complete number sentence and view some examples (and non-examples) of number sentences. Then, test your knowledge with a brief quiz.
15. What is Data Consolidation? - Definition & Overview
In this lesson, we define data consolidation as the process of combining large amounts of data, creating usable portions of information for database storage. Read on to explore data propagation and federation as well as ETL and ELT.
16. What Is Memory Management? - Requirements, Errors & Techniques
This lesson will help you understand how your computer's operating system manages memory including memory for the work you are actually doing as well as saving and storage of files. The lesson also covers some typical errors messages that sometimes appear related to memory management and some techniques for resolving those errors.
17. Associative Memory in Computer Architecture
Computers process the wealth of information we gather each day. Is it any wonder that we're constantly looking for ways to speed that up? In this lesson, we'll take a look at one method for doing this: associative memory.
18. Naive Bayes Classifier: Algorithm & Examples
Classification helps us make sense of the world. In this lesson, we'll take a look at a specific method, the Naive Bayes Classifier. At the end of the lesson, you should have a good understanding of this interesting technique.
19. Abstract Data Models
How do we simplify the vast amount of data at disposal? The answer to that is abstract data models. In this lesson, we'll take a look at data models and abstraction, and their characteristics and uses.
